A couple things. He did have to stop his stride to catch the ball the big thing that I noticed was that at that point he was "running on his heels" he wS too upright and not in a position to out run a guy. The other thing was that I think he was thinking too much about the other guy. Instead of turning up field and just running, he was too worried about the other man. He should have cut it back inside to put him on his heels and even the playing field so to speak. He is supposed to be allusive and he didn't do it.
